Rules for Changing Your Start Corral

• Blue start – You may move to Orange or Pink, but only within the same corral letter or to a corral with a higher letter. You may also move to a later wave.
• Orange start – You may move to Pink within the same corral or to a higher one. Moving to a later wave is allowed.
• Pink start – You may move to any corral with a higher letter and to any later wave.
• Exception – Runners assigned to Wave 5, Pink, Corral F cannot move to any other corral — this is the final group.

You do not need permission from organizers to change your position. Just follow the rules. You may not move to an earlier wave or to a corral with a lower letter. If a corral is full, pairs or groups must move to the back of that corral.

How the Wave System Works

Start waves are filled based on runner pace. The entire system includes approximately 60,000 participants, divided across five waves:

• Wave 1 – approx. 15,000 runners, starts at 9:10 AM
• Wave 2 – approx. 15,000 runners, starts at 9:45 AM
• Wave 3 – approx. 12,000 runners, starts at 10:20 AM
• Wave 4 – approx. 10,000 runners, starts at 10:55 AM
• Wave 5 – approx. 6,000–8,000 runners, starts at 11:30 AM

Start times are part of NYRR’s carefully planned logistics. They account for runner transport, course capacity, and safety protocols. Each wave has specific bib number ranges assigned, which you can review in my full guide:

Bib Number – What Does It Mean?

Your bib number includes your wave, corral, and start color. It’s not just an identifier — it’s the key to race-day logistics. How to read it and what each part means is explained here:

What Can You Bring to the Start?

Rules for bags, drinks, clothing, and gear are clearly defined. Not everything is allowed in the start area, and some items require advance approval. The full list is here:

Summary

Changing your start corral at the New York City Marathon 2025 is possible, but only within clearly defined rules. You cannot move to an earlier wave or to a corral with a lower letter. You can move to a later wave or to a corral with a higher letter — as long as you stay within your assigned start area or follow the allowed transitions.

The entire system is based on predicted pace and is designed to organize the start for approximately 60,000 runners.
